1. Mixer chassis

專用汽車底盤是自上料混凝土攪拌罐車組成中成本、使用中維護(hù)費(fèi)用的部分。對(duì)于底盤，主要看該底盤的發(fā)動(dòng)機(jī)功率和扭矩、油耗、輪胎、車架、駕駛舒適性及排放標(biāo)準(zhǔn)等方面。用戶在選用時(shí)除應(yīng)考慮該汽車底盤本身性能和該底盤能否得到汽車底盤制造商及時(shí)的維修支持和配件供給之外，還要考慮當(dāng)?shù)氐呐欧乓?、?gòu)買者的資金實(shí)力和對(duì)運(yùn)輸量的飽滿程度的要求，工作量越飽滿，對(duì)攪拌運(yùn)輸車的可靠性要求越高。

The chassis of special purpose vehicle is the part with the highest cost and the highest maintenance cost in use. For the chassis, focus on the chassis engine power and torque, fuel consumption, tires, frame, driving comfort and emission standards. When selecting, users should not only consider the performance of the chassis itself and whether the chassis can get timely maintenance support and parts supply from the chassis manufacturer, but also consider the local emission requirements, the buyer's financial strength and the requirements for the fullness of the transportation volume. The fuller the workload is, the higher the reliability requirements of the mixer truck are.

2.液壓傳動(dòng)件

2. Hydraulic transmission parts

混凝土攪拌運(yùn)輸車由于工況惡劣，所以對(duì)液壓傳動(dòng)件的質(zhì)量、可靠性要求相當(dāng)高。目前液壓傳動(dòng)系統(tǒng)市場(chǎng)上有兩種配置：一種是分體式配置，由液壓油泵、液壓馬達(dá)、冷卻器和減速機(jī)組成，該配置成熟可靠，維修方便；另一種是三合一式配置，由液壓油泵、三合一減速機(jī)（內(nèi)含液壓馬達(dá)、散熱器、減速機(jī)）組成，該配置集成度高，安裝方便，外形美觀，但由于液壓系統(tǒng)用油與減速機(jī)用油是同一種油，所以對(duì)油的要求較嚴(yán)格。

Due to the bad working conditions of concrete mixer truck, the quality and reliability of hydraulic transmission parts are required to be quite high. At present, there are two configurations of hydraulic transmission system in the market: one is split configuration, which is composed of hydraulic oil pump, hydraulic motor, cooler and reducer, which is mature and reliable and easy to maintain; the other is three in one configuration, which is composed of hydraulic oil pump and three in one reducer (including hydraulic motor, radiator and reducer). The configuration is highly integrated, easy to install and external The shape is beautiful, but because the hydraulic system oil and the reducer oil are the same kind of oil, so the oil requirements are more strict.

3.整車性能

3. Vehicle performance

經(jīng)改裝后的整車性能主要體現(xiàn)在操縱性、橫向穩(wěn)定性及攪拌筒的性能等方面。操縱性：主要反映在重載時(shí)駕駛員轉(zhuǎn)向的操縱感覺。攪拌車所裝混凝土為半流體，特別是坍落度較大，車輛在坡上起步時(shí)會(huì)向后移動(dòng)，選購(gòu)時(shí)要特別注意。橫向穩(wěn)定性：重載攪拌運(yùn)輸車轉(zhuǎn)彎時(shí)的速度及的高低對(duì)橫向穩(wěn)定性的影響較大。目前市場(chǎng)上8立方米攪拌車攪拌筒的傾斜角度一般為15°，也有個(gè)別是13°。角度越小，對(duì)的降低就越有利，同時(shí)在通過性和出料性方面也有改善。攪拌筒：對(duì)攪拌筒的性能產(chǎn)生影響的主要是攪拌葉片的布置。

The performance of the modified vehicle is mainly reflected in the maneuverability, lateral stability and the performance of the mixing drum. Maneuverability: mainly reflected in the steering feeling of the driver under heavy load. The concrete in the mixer truck is semi fluid, especially with large slump. When the vehicle starts on the slope, the center of gravity will move backward, so special attention should be paid when purchasing. Lateral stability: the turning speed and center of gravity of heavy haul mixer truck have great influence on lateral stability. At present, the inclination angle of the mixing drum of 8 cubic meters mixer truck is generally 15 degrees, and some of them are 13 degrees. The smaller the angle is, the more favorable it is to reduce the center of gravity and improve the trafficability and discharge performance. Mixing drum: the main factor affecting the performance of mixing drum is the arrangement of mixing blades.

4.性價(jià)比

4. Cost performance

在滿足上述要求的前提下再考慮價(jià)格因素。裝載量為8-10立方米的6×4底盤混凝土攪拌運(yùn)輸車是性價(jià)比的車型，

On the premise of meeting the above requirements, the price factor will be considered. The 6 × 4 chassis concrete mixer truck with a loading capacity of 8-10 cubic meters is the most cost-effective model,

5.售后服務(wù)

5. After sales service

混凝土攪拌運(yùn)輸車是一種專用重型車輛，保有量少，配件來源少，與一般通用汽車相比，對(duì)廠家的售后服務(wù)依賴性較大。因此，廠家是否能提供方便快捷可靠的售后服務(wù)，是選型中必須考慮的重要因素。

Concrete mixer truck is a kind of special heavy-duty vehicle, which has a small amount of possession and less sources of accessories. Compared with general motors, it depends more on the manufacturer's after-sales service. Therefore, whether the manufacturer can provide convenient, fast and reliable after-sales service is an important factor that must be considered in the selection.
